Objective: To explore the relationship between baseline clinical characteristics and hematological parameters of patients undergoing radical resection for pancreatic ductal adenocarcinoma (PDAC) and their prognosis, and to provide references for stratifying the patients' clinical risks. Methods: We retrospectively collected clinical data from 445 patients who underwent radical surgical treatment for PDAC at West China Hospital, Sichuan University between January 2010 and February 2019. Then, we conducted retrospective clinical analysis with the collected data. Data on patients' basic clinical characteristics, routine blood test results, and tumor indicators were collected to explore their effects on the postoperative overall survival (OS) of PDAC patients. Cox proportional hazards regression was used to identify factors affecting OS. Statistical analysis was performed using the SPSS 23.0 software package. Results: The postoperative median overall survival (mOS) was 17.0 months (95% CI: 15.0-19.0). The 1, 2, 3, 4, and 5-year survival rates of the patients included in the study were 60.6%, 33.4%, 19.1%, 12.7%, and 9.6%, respectively. The multivariate Cox proportional hazards model analysis demonstrated that a number of factors independently affect postoperative survival in PDAC patients. These factors include tumor location (hazards ratio [HR]=1.574, 95% CI: 1.233-2.011), degree of tumor cell differentiation (HR=0.687, 95% CI: 0.542-0.870), presence of neural invasion (HR=0.686, 95% CI: 0.538-0.876), TNM staging (HR=1.572, 95% CI: 1.252-1.974), postoperative adjuvant therapy (HR=1.799, 95% CI: 1.390-2.328), preoperative drinking history (HR=0.744, 95% CI: 0.588-0.943), and high serum CA199 levels prior to the surgery (HR=0.742, 95% CI: 0.563-0.977). Conclusion: In PDAC patients, having tumors located in the head of the pancreas, moderate and high degrees of differentiated, being free from local neurovascular invasion, being in TNM stage Ⅰ, undergoing postoperative adjuvant therapy, no history of alcohol consumption prior to the surgery, and preoperative serum CA199 being less than or equal to 37 U/mL are significantly associated with a better prognosis.

Association of magnesium intake with type 2 diabetes and total stroke: an updated systematic review and meta-analysis.

OBJECTIVE: The detailed associations between type 2 diabetes (T2D) and total stroke and magnesium intake as well as the dose-response trend should be updated in a timely manner. DESIGN: Systematic review and meta-analyses. DATA SOURCES: PubMed, Embase, Cochrane Library, Web of Science and ClinicalTrials.gov were rigorously searched from inception to 15 March 2019. ELIGIBILITY CRITERIA: Prospective cohort studies investigating these two diseases were included. DATA SYNTHESIS: Relative risk (RR) and 95% CI in random effects models as well as absolute risk (AR) were pooled to calculate the risk of T2D and stroke. Methodological quality was assessed by the Newcastle-Ottawa Scale. RESULTS: Forty-one studies involving 53 cohorts were included. The magnitude of the risk was significantly reduced by 22% for T2D (RR 0.78 (95% CI 0.75 to 0.81); p<0.001; AR reduction 0.120%), 11% for total stroke (RR 0.89 (95% CI 0.83 to 0.94); p<0.001; AR reduction 0.281%) and 12% for ischaemic stroke (RR 0.88 (95% CI 0.81 to 0.95); p=0.001; AR reduction 0.246%) when comparing the highest magnesium intake to the lowest. The inverse association still existed when studies on T2D were adjusted for cereal fibre (RR 0.79; p<0.001) and those on total stroke were adjusted for calcium (RR 0.89; p=0.040). Subgroup analyses suggested that the risk for total and ischaemic stroke was significantly decreased in females, participants with ≥25 mg/m2 body mass index and those with ≥12-year follow-up; the reduced risk in Asians was not as notable as that in North American and European populations. CONCLUSIONS: Magnesium intake has significantly inverse associations with T2D and total stroke in a dose-dependent manner. Feasible magnesium-rich dietary patterns may be highly beneficial for specific populations and could be highlighted in the primary T2D and total stroke prevention strategies disseminated to the public.

Three-dimensional vs 2-dimensional laparoscopic gastrectomy for gastric cancer: A systematic review and meta-analysis.

BACKGROUND: Both 3-dimensional (3D) laparoscopic gastrectomy (LG) and 2-dimensional (2D) LG are commonly used for gastric cancer (GC). To investigate their safety and efficacy, we performed this meta-analysis. METHODS: PubMed, The Cochrane Library, Science Direct, Embase, Scopus, and Web of Science were systematically searched to identify relevant studies. The total number of lymph node dissections (LNDs), operation time, blood loss, postoperative hospital stay, postoperative complications, and hospitalization cost were extracted as major endpoints. RESULTS: Among 904 articles that were enrolled, 9 studies were included for analysis. The 3D group was observed to have shorter operation times [95% confidence interval (CI): -0.54 to -0.06; P = .01] and less blood loss (95% CI: -0.41 to -0.19; P < .00001) than the 2D group. Compared with the 2D group, slightly higher hospitalization cost was found in the 3D group (95% CI: 0.06-0.37; P = .008). However, the outcomes among the total LNDs, postoperative hospital stay, and postoperative complications were similar. Subgroup analysis suggested that the 3D LG group had more 11p (2.22 ±â€Š1.80 vs 1.47 ±â€Š1.99, P = .019) and 8a (2.52 ±â€Š1.88 vs 1.48 ±â€Š1.43, P = .001) LNDs compared to the 2D LG group. CONCLUSIONS: 3D LG has advantages for GC, with shorter operation times, less blood loss, and possibly more LNDs. However, the cost was slightly higher than that of 2D LG.

Stereotactic Body Radiotherapy Combined with Transcatheter Arterial Chemoembolization versus Stereotactic Body Radiotherapy Alone as the First-Line Treatment for Unresectable Hepatocellular Carcinoma: A Meta-Analysis and Systematic Review.

BACKGROUND: The superiority of stereotactic body radiotherapy (SBRT) combined with transcatheter arterial chemoembolization (TACE) compared to SBRT alone as the first-line therapy for unresectable hepatocellular carcinoma (HCC) remains unclear. We conducted this meta-analysis to compare the efficiency and safety of SBRT combined with TACE (ST group) and SBRT alone (SA group). METHODS: We searched PubMed, Ovid Medline, Web of Science, Scopus, The Cochrane Library, ScienceDirect, EMBASE, Google Scholar, and CNKI (China National Knowledge Infrastructure) for related studies. We analyzed overall survival (OS), local control survival (LCS), progression-free survival (PFS), the response rate and adverse effects (AEs) between the 2 groups. RESULTS: Ten articles were included, with a total of 980 patients. The results showed that the ST (SBRT + TACE) group had a longer OS (95% CIs 0.60-0.85, p = 0.0002), a higher 5-year OS rate (95% CI 1.01-2.04, p = 0.04), a higher rate of complete response (95% CI 1.08-1.90, p = 0.01), and a higher disease control rate (95% CI 1.02-1.16, p = 0.02) than the SA (SBRT alone) group. No significant difference was found in LCS, PFS and total AEs of all grades and grades 3-5 AEs between the 2 groups. In the subgroup analysis, the patients with HCC + PVTT or treated with SBRT followed by TACE in the ST group had the same OS as those in the SA group, and the patients in the ST group had a higher incidence rate of leukopenia and fever than those in the SA group. CONCLUSION: SBRT + TACE appears to be more effective than SBRT alone in treating unresectable HCC. However, its higher incidence rate of leukopenia and fever need to be monitored.
